As someone who has past horror stories of using product that caused my skin allergy, Think Dirty is an app that I have been waiting for so long. It will let me know all the ingredients in the products, so I won't have to be a human guinea pig for new products. It will be a saviour for people like myself who has bad experience of using the wrong product for undisclosed ingredients. Looking forward to the launch of this important app!!
